1. Reliable Hydraulic Power for Roller Functions
The hydraulic pump converts engine mechanical power into hydraulic flow, powering critical roller functions including propel, vibration, and steering. Consistent pump performance ensures smooth operation and efficient compaction. Essential for highway paving, airport construction, landfill compaction, and large-scale earthwork projects.
2. Compatible with Bomag, Dynapac, and Hamm Roller Models
Direct bolt-on replacement for OEM hydraulic pump on Bomag BW series (BW120/BW140/BW180/BW200) , Dynapac CA/CC series (CA250/CA300/CC1200/CC2200) , and Hamm DV/HD series (DV70/DV90/HD110/HD140) road rollers. Often replaced alongside hydraulic oil filter (185028) , hydraulic oil, hose assemblies, and seal kits during complete hydraulic system service.
3. Durable Gear Pump Construction
Manufactured with precision-machined gears, cast iron housing, and high-grade seals for long service life in demanding compaction environments. Operating pressure up to 250 bar. For maximum hydraulic system reliability, replace pump when flow/pressure drops and inspect coupling and drive shaft for wear.
